Help me

So when I was younger I had this friend and we'd do everything together, I'd always stay at his house and stuff like that. I used to love his mum as like a second mum to me, but now I look at her a different way. She's so hot with a big ass. I want to destroy her p**** and make her deepthroat my c***. She does get very close to me when we talk and often strokes my arm and face. I think she'd like it if I f***** her but I don't know how to ask her? Should I message her? Should I make a move next time I see her? Help me
